An algorithm designed by government to set how many new homes need to be built in local areas will lead to a housing boom in the south while swathes of the north will see fewer homes built, councils warn.
The National Audit Office says the UK government needs to plan for scenarios which could reasonably occur, even if some of these may not be the desired outcome.
The right to buy policy was cited as a severe disincentive to building, as new homes might have to be sold after only three years, possibly at less than the cost of building.
Analysis shows that the sale of NHS land is fundamentally failing to produce affordable homes and is exacerbating the affordability crisis across the UK.
